How to Grow an Indoor Garden
For some, it may seem challenging or even impossible to grow an indoor garden. Sure, a big garden full of vegetables and herbs is a dream of many people. But, if you don’t have the space, resources, or capabilities, growing indoors is a fantastic option. And, it’s not as challenging as it may seem.
What stops people from growing a garden?
Apartment dwellers often say they don’t have space for a large outdoor garden. People who live in cold climates find it exceptionally challenging to grow an outdoor garden for much of the year. Sometimes physical challenges present, and people can’t manage the amount of labor a large garden requires.
These are all valid reasons. However, there are many reasons to grow food. For preppers, growing food is one way to become a producer and more self-reliant. Maybe you want to grow some fresh greens and herbs in the winter. Or, perhaps you want to contribute to your family’s food supply. Whatever your reasons are for not doing it, growing indoors is the solution.
What plants can I grow in an indoor garden?
Lots of plants can be grown indoors! You’re only limited by the amount of space and time you want to commit. For example, leafy green vegetables like lettuce, kale, and spinach will do great indoors, and they don’t take up much space to grow.
Herbs like rosemary, thyme, parsley, basil, and chives can all be grown year-round on a sunny windowsill. But if you have space and resources to create the right conditions, you can grow things like cucumbers, tomatoes, and even peppers indoors.
When you’re deciding what to grow, think about what your goals are. Growing things your family likes to eat is a great place to start. If you love to cook from scratch, you might enjoy having fresh herbs just a few steps away from the kitchen. Fresh greens pack a lot of nutrition and can make a significant difference if you’re living off of stored food.
Here are the basic requirements you’ll need to grow an indoor garden and to keep your plants happy and healthy.
If you have a bright, south-facing window with enough sunlight, you can probably grow most greens and herbs on the windowsill or a shelf in front of the window. But many vegetables, like cucumbers and tomatoes, will grow best with about 12 hours of light every day.
Most people don’t have enough natural light coming into their homes to keep plants healthy and happy indoors all year round. You’ll probably have to provide supplemental lighting, at least in the shorter days of winter.
For leafy plants like greens and herbs, regular shop lights are all you need. But if you want to grow fruiting plants like tomatoes, you’ll need to invest in proper, full-spectrum grow lights. Position the lights about three inches above your plants and raise them as the plants grow.
Observe your plants carefully. If they seem leggy or they’re turning yellow, they may not be getting enough light. You want your plants to be lush and green with nice thick stems.
You’re going to need containers to grow an indoor garden. There are many options, depending on your preferences. To save space, you could start your seeds in small trays and then move them to large containers later on. Having several large pots in your growing area to plant your seeds or start plants directly into them is also an option.
If you choose to plant more than one plant in the large containers, be sure the plants have plenty of room to grow. If the plants are too crowded, their roots won’t have enough space, and they won’t be as productive or healthy. Drainage is also vital for container-grown plants. Ensure your pots have plenty of holes in the bottom and place a tray underneath them to protect your floor.
You may want to consider growing your plants vertically on trellises, shelves, or in hanging baskets. Vertical growing and farming are popular in urban areas because they allow you to grow more food in less space. You could even create your own small-scale, vertical hydroponics set up for easy maintenance and maximum production.

Temperature and good airflow
Every plant has its requirements for air and soil temperature. You’ll need to do some research to see what the plants you intend to grow prefer. Some seeds are pretty picky about soil temperatures for germination. Once they’re well established, it’s okay if the temperatures swing a bit in either direction. However, you’ll want to try to keep it as close as possible to ideal growing conditions for maximum production.
For some general guidelines, most greens do best at temperatures between 65 and 70 degrees. Peppers and tomatoes like it warmer: upper 70s to mid-80s is ideal. And most herbs are happiest somewhere in the middle.
Good circulation is crucial for preventing disease and growing strong, thick stems. It’s also helpful for pollination on fruiting plants like cucumbers, tomatoes, and peppers. If your growing space has a window, leave it open for several hours each day to allow the breeze to blow through. Or use a fan to create air movement.
Growing medium and fertilizer
Keep in mind when you grow an indoor garden, plants can’t spread their roots in search of nutrients. Plants grown in containers require high-quality potting soil and regular fertilization. You can choose a potting mix that contains slow-release fertilizer or use a once-a-week liquid fertilizer formulated for veggies and herbs.
If you’re growing in a hydroponic system, you can use perlite, vermiculite, coco coir, gravel, or clay pebbles as your growing medium. Then select a hydroponic nutrient for veggies and herbs and add it to your system as directed by the manufacturer.
Final tips for growing an indoor garden
Harvesting from your plants regularly is essential for keeping production levels high. Many greens can be harvested with the cut and come again method for a continuous harvest. Just be careful not to cut more than one-third of the leaves at a time.
Although every variety is different, most greens will eventually bolt and become bitter. To have a continuous supply of leafy greens, you’ll want to start new plants regularly. Other vegetables and herbs will grow much longer before they need to be replaced. Many herbs are perennial, and perennials are long-term investments for a self-sufficient garden.
